Ultimate Guide to Leadership Assessment

Better Data. Better Leaders.

Every company stands and falls with its leaders.

There's nothing more critical to success than the people you choose to lead. But of course, no one will be perfect. Every leader has unique strengths and challenges, some of which you can develop and some you can't. The key to it all is knowledge. And that's why we’ve created this guide to leadership assessment

In recent years, we’ve seen a major movement in HR to build data into their leadership processes. We all recognize that it’s not enough to make these crucial decisions based on gut feeling alone. After all, we’re only human, subject to our own biases.  

This is especially important as businesses turn their focus to diversity and inclusion. We need to be thinking differently about people and considering all angles of our talent strategy. We can’t assume that the superstar leadership profile of the past will stay the same for the future. 

That’s why so many clients are now trying to bring leadership assessment into their strategy. However, leadership assessment can be complex. It’s not enough to simply have data. You need the right data for the right purpose.  

We created this guide to leadership assessment to help HR professionals get started. We want you to understand the types of data you can get, and how you can leverage them.

How to Use This Guide 

This is designed to be a practical guide to leadership assessment. It’s based on the common questions that we hear from our HR clients every day. While we have a lot of industrial-organizational psychologists doing excellent research behind the scenes, this is not a whitepaper or research piece. Rather, it is advice based on our experience working with clients for five decades to successfully implement leadership assessment. 

In short, this is our advice on what works and what doesn’t in the real day-to-day work of HR.  

Note that this is a “living” guide to leadership assessment. That is, we intend to update it as we explore new areas in assessment, get new data, and most importantly, based on your questions. So if you have a burning question about leadership assessment, please send it our way at info@ddiworld.com. You can be our inspiration for new sections!
